Narrative:
Challenger 604 (cl-604) departed for a reposition flight. On the initial climb up to 36;000 ft the outer ply of the pilot's side windscreen broke. The windscreen cracked completely from top to bottom vertically. The crew donned the oxygen mask and asked to stop the climb. The crew then asked to slow and descend. The crew followed all checklist items. The crew had to dump fuel to make landing weight. Crew was cleared by center to dump on our route back to [departure airport]. The crew's main concern was that the outer glass of the windscreen would break off and enter the left engine. The aircraft landed safely.
